The cover plate is provided with a liquid passing port, or at least a partial region of the drainage channel not covered by the cover plate forms the liquid passing port. The liquid flowing out of the liquid discharge port flows into the drainage channel through the liquid passing port.

[0010] In some embodiments, the cover plate has an inclined plate portion that extends downwardly and obliquely in a direction close to the liquid passing port for guiding the liquid on the upper surface of the inclined plate portion to the liquid passing port.

[0040] Please refer to Figures 3 to 10 , the embodiment of the present application provides a base device 10, including a base 11 and a liquid cooling device 12.

[0041] The base 11 has an air duct through which air flows. Please refer to Figure 5 and Figure 9 , Figure 5 and Figure 9 The arrows in which indicate the flow path of the air in the air duct.

[0042] Please refer to Figure 8 , the base 11 has a drainage channel 116. The air duct includes a first region 115. The drainage channel 116 is located on one side of the first region 115 along the first direction of the base device 10. The first region 115 can direct the liquid on its surface to the drainage channel 116. That is to say, the water in the first region 115 needs to be first collected into the drainage channel 116 and discharged from the base device 10 through the drainage channel 116.

[0043] Please refer to Figure 3 , the liquid cooling device 12 is at least partially disposed in the first region. After the condensed water generated during the condensation and dehumidification of the air flow by the liquid cooling device 12 flows to the bottom wall 115a of the first region 115, it flows through the communication port 1161 to the drainage channel 116 and then is discharged to the outside of the base device 10 through the drainage channel 116, so that the condensed water can be discharged in time.

[0044] The liquid cooling device 12 has a liquid discharge port 1212 for discharging the coolant of the liquid cooling device 12.

[0045] Specifically, coolant can be introduced into the liquid cooling device 12. During the flow of the coolant in the liquid cooling device 12, it is beneficial to keep the outer surface of the liquid cooling device 12 at a relatively low temperature. When the air flow in the air duct flows through the outer surface of the liquid cooling device 12, heat exchange occurs between the liquid cooling device 12 and the air flow. The liquid cooling device 12 absorbs the heat of the air flow and at the same time transfers the heat to the coolant in the liquid cooling device 12. The coolant heats up while the temperature of the air flow drops. The water vapor in the air flow reaches the saturation state and condenses into condensed water on the outer surface of the liquid cooling device 12. The condensed water is discharged to the bottom wall 115a of the first region 115, thereby achieving the purpose of condensing and dehumidifying the air flow by the liquid cooling device 12. After the coolant in the liquid cooling device 12 participates in the above condensation and dehumidification process, the coolant is discharged from the liquid discharge port 1212.

[0046] The specific type of the coolant is not limited. In some embodiments, the coolant is water, which can be tap water, brine, etc. In some other embodiments, the coolant can also be other liquids.

[0047] In some embodiments, the liquid drain port 1212 is located above the drain channel 116, such that the coolant of the liquid cooling device 12 can be directly drained to the drain channel 116 through the liquid drain port 1212, and then discharged outside the base device 10 through the drain channel 116. That is to say, a large amount of coolant discharged by the liquid cooling device 12 does not need to pass through the bottom wall 115a of the first region 115. On the one hand, it can ensure that the coolant of the liquid cooling device 12 is discharged in time to ensure the drainage capacity of the base device 10, and at the same time, it can also reduce the influence of the coolant discharged by the liquid cooling device 12 on other components in the first region 115.

[0048] Exemplarily, as Figure 3 shown, the base device 10 further includes a cover plate 16. The cover plate 16 is disposed on the top side of the drain channel 116. By providing the cover plate 16 in the drain channel 116, it is possible to avoid as much as possible the water in the drain channel 116 forming water vapor under the negative pressure of the air flow and entering the downstream of the air duct, thereby avoiding as much as possible the water vapor entering the first laundry treatment chamber 21.

[0049] In some embodiments, the liquid passing port 161 is provided on the cover plate 16, or at least a part of the region of the drain channel 116 not covered by the cover plate 16 forms the liquid passing port 161. That is to say, the liquid passing port 161 only needs to be ensured to be on the top side of the drain channel 116, and there is no need to limit the formation manner of the liquid passing port 161.

[0050] It should be noted that when the liquid passing port 161 is provided on the cover plate 16, the cover plate 16 independently defines the shape of the liquid passing port 161. The region not covered by the cover plate 16 means that the liquid passing port 161 is outside the overall contour of the appearance of the cover plate 16. For example, if the length of the drain channel 116 is 100 cm and the length of the cover plate 16 is 80 cm, and there is a 20 cm interval between the end of the cover plate 16 and the end of the drain channel 116, then this interval constitutes the above-mentioned liquid passing port.

[0051] The liquid flowing out of the liquid drain port 1212 flows into the drain channel 116 through the liquid passing port 161. That is, a large amount of coolant of the liquid cooling device 12 can be directly drained to the drain channel 116 through the liquid drain port 1212 and the liquid passing port 161, and then discharged outside the base device 10 through the drain channel 116. Thus, the coolant of the liquid cooling device 12 can be discharged in time.

[0052] Exemplarily, the first direction is Figure 3 、 Figure 5 、 Figure 8 and Figure 9 the direction shown in

[0053] As Figure 9 shown, in some embodiments, the base device 10 further includes an evaporator 13, and the evaporator 13 is used for condensing and dehumidifying the air flow.

[0054] It should be noted that, in some embodiments, the evaporator 13 may be located upstream of the liquid cooling device along the air flow direction, that is, the air flow first passes through the evaporator 13 and then through the liquid cooling device 12. In other embodiments, the evaporator 13 may also be located downstream of the liquid cooling device 12 along the air flow direction, that is, the air flow first passes through the liquid cooling device 12 and then through the evaporator 13.

[0055] In some embodiments, such as Figure 9 shown, the base device 10 further includes a condenser 14, and the condenser 14 is disposed downstream of the evaporator 13 and the liquid cooling device 12 along the air flow direction. The condenser 14 is used to heat the air flow after condensation and dehumidification.

[0056] It can be understood that the condenser 14 being disposed downstream of the evaporator 13 and the liquid cooling device 12 along the air flow direction means that the air flow in the air duct needs to pass through the evaporator 13 and the liquid cooling device 12 first and then enter the condenser 14, but the order of the air flow passing through the evaporator 13 and the liquid cooling device 12 is not limited.

[0057] In the embodiments of the present application, the case where the evaporator 13 is located downstream of the liquid cooling device 12 along the air flow direction is taken as an example for description. In this embodiment, the air flow first passes through the liquid cooling device 12, then through the evaporator 13, and then enters the condenser 14.

[0058] It should be noted that the evaporator 13 and the condenser 14 are part of the heat pump system. Specifically, the heat pump system further includes a compressor, a throttling device, etc. The compressor, the evaporator 13, and the condenser 14 are connected in series in the refrigerant circuit.

[0059] The working principle of the heat pump system is as follows: The compressor sucks in low-pressure gaseous refrigerant, compresses it and discharges it as high-pressure gas. The discharged high-pressure gaseous refrigerant enters the condenser 14, and the refrigerant is cooled by the normal-temperature air around the condenser 14 and condenses into high-pressure liquid (while transferring heat to the surrounding air). That is to say, the air around the condenser will be heated and its temperature will rise; the high-pressure liquid refrigerant flows through the throttling device to be throttled and depressurized, and then becomes a low-pressure and low-temperature gas-liquid two-phase mixture. The gas-liquid two-phase mixture enters the evaporator 13, and the liquid refrigerant in it evaporates and cools (while absorbing heat from the surrounding air). That is to say, the air around the evaporator 13 will be cooled and its temperature will drop. The refrigerant is sucked into the compressor again for pressurization, and so on, cycling continuously to achieve heat exchange.

[0060] Please refer to Figure 1 and Figure 2, embodiments of the present application further provide a laundry treatment device, including a first cylinder assembly 20 and the base device 10 of any embodiment of the present application. The first cylinder assembly 20 has a first laundry treatment chamber 21, and the air duct is communicated with the first laundry treatment chamber 21. The first cylinder assembly 20 is used for caring for clothes.

[0061] The laundry treatment device can at least be used for drying clothes.

[0062] The drying principle of the laundry treatment device provided by the embodiments of the present application is as follows: The humid and hot air flow discharged from the first laundry treatment chamber 21 enters the air duct, undergoes the first condensation and dehumidification by the liquid cooling device 12, then undergoes the second condensation and dehumidification by the evaporator 13. The condensed air flow is heated by the condenser 14, and the heated air flow returns to the first laundry treatment chamber 21 through the air duct again. Such a cycle is carried out to achieve continuous drying of the clothes.

[0063] In this embodiment, the liquid cooling device 12 performs the first condensation and dehumidification on the air flow entering the air duct, reduces the temperature and humidity of the air flow, and intercepts a part of impurities such as lint. The air flow after the first condensation and cooling flows through the evaporator 13 for the second condensation and cooling, further condensing and dehumidifying the air flow. Since the air flow has undergone the first condensation and dehumidification before flowing through the evaporator 13, therefore, on the premise of ensuring the condensation and dehumidification effect on the air flow, it helps to reduce the evaporation temperature of the evaporator 13, thereby reducing the power consumption of the heat pump system.

[0064] It should be noted that the low-temperature drying air flow is relative to the humid and hot air flow, and the temperature of the low-temperature drying air flow is lower than that of the humid and hot air flow. The low temperature in the embodiments of the present application can be room temperature.

[0065] In some embodiments, please refer to Figure 1 , the laundry treatment device includes a box body, a second cylinder assembly 30, and a rack 40 disposed in the box body.

[0066] The rack 40 is the main support structure, and is used for the fixed installation and support of other components of the laundry treatment device.

[0067] The base device 10 is disposed on the rack 40, and the base device 10 and its load transfer the acting force to the rack 40.

[0068] In some embodiments, as Figure 2 shown, the rack 40 at least includes four columns 41, and the four columns 41 respectively extend in the height direction. In the horizontal plane projection, the four columns 41 are distributed at the four vertices of a quadrilateral.

[0069] Exemplarily, as Figure 2 shown, the base device 10 can be respectively connected to the above four columns 41. The base device 10 is located within the area defined by the four columns 41.

[0070] The base device 10 divides the space inside the box into at least a first space and a second space in the height direction. The first cylinder assembly 20 is arranged in the first space, and the second cylinder assembly 30 is arranged in the second space.

[0071] It should be noted that, as Figure 1 , Figure 2 and Figure 3 shown, the height direction of the laundry treatment device is the top-bottom direction, which can also be called the up-down direction. It includes both the direction from the top to the bottom and the direction from the bottom to the top.

[0072] In some embodiments, the first laundry treatment chamber 21 can at least dry the laundry. The second cylinder assembly 30 has a second laundry treatment chamber 31, and the second laundry treatment chamber 31 can at least wash the laundry.

[0073] In some embodiments, the first space is located above the second space, that is, the position of the first cylinder assembly 20 is higher than the position of the second cylinder assembly 30. In other embodiments, the first space can also be located below the second space, that is, the position of the second cylinder assembly 30 is higher than the position of the first cylinder assembly 20.

[0074] In some embodiments, as Figure 4 , Figure 6 and Figure 7 shown, the cover plate 16 has an inclined plate portion 162. The inclined plate portion 162 extends downward obliquely in the direction close to the liquid passing port 161, and is used to guide the liquid on the upper surface of the inclined plate portion 162 to the liquid passing port 161. That is to say, the inclined plate portion 162 can provide guidance for the liquid on its upper surface by virtue of its tendency to extend downward obliquely in the direction towards the liquid passing port 161, so that the liquid on the upper surface of the inclined plate portion 162 can enter the drainage channel 116 through the liquid passing port 161. In addition, even if the liquid discharged from the liquid discharge port 1212 is discharged onto the upper surface of the inclined plate portion 162, the inclined plate portion 162 can also drain the liquid to the liquid passing port 161, thereby being able to reduce the requirements for the size and position of the liquid passing port 161 and the liquid discharge port 1212.

[0075] In this embodiment, the number of the inclined plate portions 162 is not limited. It can be arranged around the circumferential side of the liquid passing port 161, or can be arranged only on one side or multiple sides of the liquid passing port 161.

[0076] It should be noted that the inclined plate portion 162 refers to a plate-like structure that has a tendency to extend obliquely downward in the direction close to the liquid passing port 161. The plate portion can be a flat plate structure, or can not be a flat plate structure, such as a curved plate-like structure, a wavy plate-like structure, etc. The upper surface of the inclined plate portion 162 can be a smooth surface, or protrusions can be provided on the upper surface of the inclined plate portion 162.

[0077] In some embodiments, such as Figure 4 As shown, the inclined plate portion 162 is disposed on the downstream side of the air duct near the liquid outlet 161 along the airflow direction. In this embodiment, the inclined plate portion 162 not only guides the liquid on its upper surface, but also its upwardly inclined surface along the airflow direction prevents the liquid on its upper surface from flowing toward the downstream of the air duct under the negative pressure of the airflow, thereby minimizing the liquid on its upper surface from flowing downstream of the air duct under the negative pressure of the airflow.

[0078] In some embodiments, such as Figure 6 and Figure 7 As shown, the cover plate 16 is partially recessed downward to form a recessed structure 163, and the liquid outlet 161 is disposed in the recessed structure 163. The recessed structure 163 has a certain liquid collection capacity and can collect liquid around the liquid outlet 161, thereby helping to reduce the probability of liquid flowing through the liquid outlet 161 overflowing or splashing outside the recessed structure 163, thereby helping to improve the drainage capacity of the base device 10.

[0079] It should be noted that the recessed structure 163 refers to a structure formed by a partial downward recess of the cover plate 16, but there is no limitation on the degree of the downward recess of each part of the cover plate 16, that is, the depths of each area of the recessed structure 163 can be the same or different.

[0080] In some embodiments, such as Figure 6 and Figure 7 As shown, the recessed structure 163 includes a recessed bottom plate 1631, and the recessed bottom plate 1631 includes a first end 1632 and a second end 1633, and the second end 1633 is located downstream of the first end 1632 along the airflow direction of the air duct, that is, the first end 1632 and the second end 1633 are arranged opposite to each other along the airflow direction, and the first end 1632 and the second end 1633 limit the size of the recessed structure 163 along the airflow direction.

[0081] For example, see Figure 6 and Figure 7 , the recessed bottom plate 1631 extends downwardly in an inclined direction from the second end 1633 to the first end 1632, that is, the depth of the recessed structure 163 increases from the second end 1633 to the first end 1632. The closer to the first end 1632, the stronger the water collection capacity of the recessed structure 163. The recessed bottom plate 1631 can guide the liquid on its upper surface from the second end 1633 to the first end 1632, thereby helping to improve the liquid collection capacity of the recessed structure 163.

[0082] For example, Figure 6 and Figure 7As shown, the liquid passing port 161 is provided on the sunken bottom plate 1631. That is to say, along the direction from the second end 1633 to the first end 1632, the sunken bottom plate 1631 can guide the liquid on the upper surface of the sunken bottom plate 1631 to the liquid passing port 161. Moreover, the liquid passing port 161 is provided on the sunken bottom plate 1631. On the one hand, it helps the sunken bottom plate 1631 to directly guide the liquid to the liquid passing port 161. On the other hand, it is convenient for the coolant discharged from the drain port 1212 to directly flow through the liquid passing port 161 under the action of gravity.

[0083] In some embodiments, in the horizontal plane projection, the projection of the drain port 1212 is within the projection range of the liquid passing port 161. That is to say, along the height direction of the laundry treatment device, the coolant discharged from the drain port 1212 can directly flow through the liquid passing port 161 under the action of gravity and enter the drainage channel 116, which helps to improve the drainage efficiency. Moreover, there is no need to arrange a drainage pipe from the drain port 1212 to the liquid passing port 161, which helps to save the layout space and layout cost.

[0084] In some embodiments, the liquid passing port 161 is arranged close to the first end 1632. It can be understood that the first end 1632 of the sunken bottom plate 1631 is the lowest position of the sunken bottom plate 1631 along the height direction. That is to say, after the sunken bottom plate 1631 guides the liquid on its upper surface to the first end 1632, almost all the liquid can enter the drainage channel 116 through the liquid passing port 161. The liquid enters the drainage channel 116 through the liquid passing port 161, which helps to prevent the water collected by the sunken structure 163 from remaining on the sunken bottom plate 1631. Moreover, after the sunken bottom plate 1631 guides the liquid on its upper surface to the first end 1632, the liquid at the first end 1632 needs to overcome more resistance to enter the downstream of the air duct. That is to say, it is more difficult for the liquid at the first end 1632 to enter the downstream of the air duct under the negative pressure of the air flow.

[0085] Refer to Figure 6 and Figure 7 , the inclined plate portion 162 forms a part of the sunken bottom plate 1631. That is to say, there is no need to separately manufacture the inclined plate portion 162. Just opening the liquid passing port 161 on the inclined sunken bottom plate 1631 can realize that the inclined plate portion 162 is arranged on the side of the liquid passing port 161 close to the air duct along the air flow direction, which helps to simplify the manufacturing process.

[0086] It should be noted that the sunken bottom plate 1631 refers to the physical structure where the bottom wall of the sunken structure 163 is located. The form of the sunken bottom plate 1631 is not limited. It can be a flat plate structure or not, such as a curved plate structure, etc.; the upper surface of the sunken bottom plate 1631 can be a smooth surface, or protrusions can be provided on the upper surface of the sunken bottom plate 1631.

[0087] In some embodiments, one end of the evaporator 13 along the first direction is at least partially located above the inclined plate portion 162. This effectively utilizes the space above the drainage channel 116, helping to reduce the space occupied by the evaporator 13 in the first area 115 in the first direction, thereby making the base device 10 more compact. Furthermore, a portion of the condensed water generated by the evaporator 13 during dehumidification of the airflow can be directed through the inclined plate portion 162 to the liquid outlet 161.

[0088] In some embodiments, one end of the evaporator 13 along the first direction is at least partially supported on the cover plate 16. The cover plate 16 can provide relatively stable support for one end of the evaporator 13. At the same time, part of the weight of the evaporator 13 can generate downward pressure on the cover plate 16, so that the cover plate 16 can be stably covered on the drainage channel 116, and the cover plate 16 can be avoided as much as possible from being separated from the drainage channel 116 under the action of the water flow in the drainage channel 116 or the negative pressure of the air flow in the air duct, which helps to improve the stability of the cover plate 16.

[0089] In some embodiments, one end of the liquid cooling device 12 along the first direction is supported on the bottom wall 115a of the first region 115, and the other end is supported on the cover plate 16. This effectively utilizes the space above the drainage channel 116, helping to reduce the space occupied by the liquid cooling device 12 in the first region 115 in the first direction. Furthermore, the cover plate 16 provides relatively stable support for one end of the liquid cooling device 12. Furthermore, some of the weight of the liquid cooling device 12 exerts downward pressure on the cover plate 16, ensuring that the cover plate 16 remains stably positioned over the drainage channel 116. This minimizes the cover plate 16 from being dislodged from the drainage channel 116 due to the water flow within the drainage channel 116 and / or the negative pressure of the airflow within the air duct, thereby improving the stability of the cover plate 16.

[0090] For some examples, see Figure 6 and Figure 7 A portion of the top surface of the cover plate 16 is recessed downward to form a recessed platform 164, with the other end of the liquid cooling device 12 supported on the recessed platform 164. The recessed platform 164 is provided to ensure that the portion of the top surface of the cover plate 16 supporting the liquid cooling device 12 is flush with the portion of the upper surface of the bottom wall 115a of the first region 115 supporting the liquid cooling device 12. Furthermore, the recessed platform 164 serves to limit the position of the liquid cooling device 12, preventing it from shaking along the airflow direction. Furthermore, the recessed platform 164 provides stable pressure on the liquid cooling device 12, thereby ensuring that the cover plate 16 is more stably positioned within the drainage channel 116.

[0091] In some embodiments, such as Figure 10As shown, the base 11 includes a bottom wall portion 11a. A part of the bottom wall portion 11a is recessed downward to form a drainage channel 116, and the liquid flows in the space within the drainage channel 116. At this time, the position of the bottom wall 116a of the drainage channel 116 is lower than the bottom wall 115a of the first region 115, so that the water in the first region 115 can flow into the drainage channel 116.

[0092] It should be noted that the bottom walls in the bottom wall 116a of the drainage channel 116 and the bottom wall 115a of the first region 115 refer to the surfaces. That is, the bottom wall 116a of the drainage channel 116 refers to the upper surface of the bottom wall 116a of the drainage channel 116, and the bottom wall 115a of the first region 115 refers to the upper surface of the bottom wall 115a of the first region 115. The bottom wall portion 11a of the base 11 refers to a solid structure.

[0093] Exemplarily, as Figure 8 shown, the drainage channel 116 includes a first side wall 1162 and a second side wall 1163 that are oppositely arranged in the first direction. The first side wall 1162 and the second side wall 1163 both extend in the second direction, and the second direction intersects the first direction, for example, is substantially perpendicular.

[0094] The cover plate 16 is supported at the tops of the first side wall 1162 and the second side wall 1163. That is, the first side wall 1162 and the second side wall 1163 can provide support for the cover plate 16.

[0095] The first side wall 1162 is located on the side of the second side wall 1163 close to the first region 115, and a communication port 1161 is provided on the first side wall 1162. That is, the first side wall 1162 is the junction of the first region 115 and the drainage channel 116. The communication port 1161 is provided on the first side wall 1162, and the liquid on the bottom wall 115a of the first region 115 flows into the drainage channel 116 through the communication port 1161.

[0096] Exemplarily, the second direction is Figure 3 、 Figure 5 、 Figure 8 and Figure 9 the direction shown by the second direction in

[0097] In some embodiments, as Figure 5 and Figure 8 shown, the bottom wall 115a of the first region 115 includes a first part 1151 and a second part 1153. As Figure 9 and Figure 10 shown, at least part of the liquid cooling device 12 is located above the second part 1153. That is, some of the condensed water precipitated during the condensation and dehumidification process of the liquid cooling device 12 can be directly discharged to the second part 1153.

[0098] The position of the second part 1153 is lower than that of the first part 1151, so that the liquid in the first part 1151 can drain towards the second part 1153 and then flow through the second part 1153 to the drainage channel 116. The second part 1153 functions as a drainage guide; at the same time, it also enables the condensed water generated during the air flow condensation and dehumidification process by the liquid cooling device 12 to not flow back to the first part 1151 as much as possible, thereby reducing the impact of the liquid in the second part 1153 on the components installed in the first part 1151 as much as possible.

[0099] One end of the second part 1153 extends to the communication port 1161. That is to say, the liquid in the second part 1153 is directly drained to the drainage channel 116 through the communication port 1161. In this embodiment, there is no need to set up other guiding structures, which helps to save the layout space of the first area 115 and also saves manufacturing costs.

[0100] In some embodiments, such as Figure 10 shown, the second part 1153 slopes downward along the first direction towards the communication port 1161, so that the liquid in the second part 1153 can be drained to the drainage channel 116 more smoothly. At the same time, it also makes the interval between the end of the second part 1151 close to the drainage channel 116 and the cover plate 16 larger, that is, it helps to make the size of the communication port 1161 larger in the height direction, which helps the liquid in the second part 1153 to be drained to the drainage channel 116 more timely.

[0101] In some embodiments, the position of the bottom surface of the liquid cooling device 12 is higher than the junction position of the first part 1151 and the second part 1153, where the junction position refers to the edge of the first part 1151 close to the second part 1153. On the one hand, it reduces the probability of the liquid cooling device 12 blocking the condensed water flowing from the first part 1151 to the second part 1153. On the other hand, it also reduces the probability of the condensed water flowing from the first part 1151 to the second part 1153 scouring the liquid cooling device 12.

[0102] In some embodiments, such as Figure 5 and Figure 8 shown, a step structure 1154 is formed at the junction of the first part 1151 and the second part 1153. The step structure 1154 can play a good role in blocking the water in the second part 1153, so that the water in the second part 1153 cannot flow back to the first part 1151 with the air flow, improving the drainage effect of the base device 10.

[0103] In some embodiments, please refer to Figure 8 and Figure 10Bottom wall 115a of first region 115 further includes a flat portion 1152, which is located on a side of second portion 1153 away from drainage channel 116. Flat portion 1152 is positioned higher than second portion 1153. Flat portion 1152 supports one end of liquid cooling device 12 in the first direction away from drainage channel 116, while the other end of liquid cooling device 12 in the first direction is supported on cover plate 16. In other words, flat portion 1152 and a portion of the top surface of cover plate 16 support bottom surface 12b of liquid cooling device 12.

[0104] In the embodiment with the sink 164, the flat portion 1152 and the top surface of the sink 164 form a support for the bottom surface 12b of the liquid cooling device 12. It can be understood that the top surface of the sink 164 and the flat portion 1152 are flush in the height direction.

[0105] In this embodiment, the second portion 1153 extends downwardly in a direction from the flat portion 1152 to the communication opening 1161 .

[0106] In some embodiments, such as Figure 3 As shown, the liquid cooling device 12 includes a liquid cooling pipe 121 for circulating the coolant. The end of the liquid cooling pipe 121 forms a drain port 1212. The liquid cooling pipe 121 also includes a liquid inlet 1211. The liquid inlet 1211 and the drain port 1212 are located on the same side of the liquid cooling device 12 along the first direction. The liquid inlet 1211 and the drain port 1212 are located on the same side of the liquid cooling device 12 to facilitate piping.

[0107] Moreover, the liquid inlet 1211 needs to be connected to the water supply component. The liquid inlet 1211 and the liquid discharge port 1212 are both arranged above the drainage channel 116. The area above the drainage channel 116 can provide sufficient space for the liquid inlet 1211 and the water supply component.

[0108] In some embodiments, the liquid inlet 1211 is positioned higher than the liquid outlet 1212. The height difference between the liquid inlet 1211 and the liquid outlet 1212 allows the water in the liquid cooling circuit 121 to flow under its own gravity, thereby reducing the water pressure requirement of the water flow in the water inlet 1211.

[0109] In some embodiments, the liquid cooling device 12 further includes fins, through which liquid cooling pipes 121 extend. The liquid cooling pipes 121 transfer their cooling energy to the fins, which, when in contact with the airflow, transfer the cooling energy to the airflow. The fins help increase the contact area between the liquid cooling device 12 and the airflow, thereby improving the condensation and dehumidification effect.
